18 April 2017  |  Archive The  XSLT Working Group  has published a Proposed Recommendation of  XSL Transformations (XSLT) Version 3.0 . This specification defines the syntax and semantics of XSLT 3.0, a language designed primarily for transforming XML documents into other XML documents. XSLT 3.0 is a revised version of the XSLT 2.0 Recommendation published on 23 January 2007. The primary purpose of the changes in this version of the language is to enable transformations to be performed in streaming mode, where neither the source document nor the result document is ever held in memory in its entirety. Another important aim is to improve the modularity of large stylesheets, allowing stylesheets to be developed from independently-developed components with a high level of software engineering robustness. Comments are welcome through  19 May .

19 February 2015 Today the XSLT Working Group and the XML Query Working Group jointly published a Candidate Recommendation for, and invite implementations of, XSLT and XQuery Serialization 3.1 . The serialization specification defines output methods in XML, HTML, plain or formatted text and JSON. The specification returned to Working Draft to add an Adaptive serialization closer to industry practice for ad-hoc formatting of results. An extensive test suite is available.

9 October 2014 Today the XQuery Working Group published a Last Call Working Draft of XQuery 3.1 and XQueryX 3.1 . Additional supporting documents were published jointly with the XSLT Working Group : a Last Call Working Draft of XPath 3.1 , together with XPath Functions and Operators , XQuery and XPath Data Model , and XSLT and XQuery Serialization . XQuery 3.1 and XPath 3.1 introduce improved support for working with JSON data with map and array data structures as well as loading and serializing JSON; additional support for HTML class attributes, HTTP dates, scientific notation, cross-scaling between XSLT and XQuery and more. Comments are welcome through 7 November 2014 . Learn more about the XML Activity .

The XML Query Working Group and the XSLT Working Group have published a new version of the Candidate Recommendation of XPath and XQuery Functions and Operators 3.0 . The new version reflects changes and clarifications that have been made during the CR period, primarily as a result of feedback from implementors outside the two Working Groups. The document describes various functions and operators that work on XML Schema-compatible data types for use in XPath, XSLT, XQuery, XQueryX, SPARQL and other languages.

28 March 2013 The XSLT Working Group and the XML Query Working Group have published a Candidate Recommendation of XSLT and XQuery Serialization 3.0 . This document defines serialization of an instance of the data model as defined in XQuery and XPath Data Model (XDM) 3.0 into a sequence of octets. Serialization is designed to be a component that can be used by other specifications such as XSL Transformations (XSLT) Version 3.0 or XQuery 3.0: An XML Query Language.
